Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment protection, in particular to a leakage prevention device for a retaining roller between frames. Background Art

[0002] The retaining roller, also known as the vertical roller or wing roller, is an important component of conveying machinery and is mainly used on belt conveyors. The main function of the retaining roller is to be installed on both sides of the conveyor by connecting with the self-aligning bracket to achieve specific operating goals. When the conveyor belt deviates during operation, the retaining roller can rotate around the rotating shaft on the rotating mechanism through its own motion rod, thereby driving the entire roller group to rotate an angle to help the conveyor belt return to the normal running track. This design not only helps to correct the deviation of the belt, but also ensures that the belt runs under the appropriate tension state by adjusting the tension, thereby maintaining the stable operation of the conveyor. In addition, the retaining roller can also play a role in buffering and shock absorption, reducing the impact force of the material on the belt and ensuring the smooth transportation of the material. The number and arrangement of the retaining rollers have a significant impact on the performance of the belt conveyor. Generally, the more the number of retaining rollers, the smaller the material resistance, the relatively lower the energy consumption, the smaller the belt speed change, and at the same time affects the material falling position and unloading speed. With the development of society, when the retaining roller needs to be protected, a leak-proof device is used.

[0003] At present, most of the anti-leakage devices of the retaining roller are anti-leakage through a single rubber ring. Since the retaining roller will constantly rub against the rubber ring during the rotation process, the end face of the rubber ring will be severely worn, causing the lubricating oil to flow out from the rotating part of the retaining roller, thereby reducing the sealing effect of the rubber ring.
